DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 248,888, dated November1, 1881, Application filcdlLIay 13,1881. (N0 model.)

To all whom it may concern:

Be it known that I, \VALTER Scorn, a subject of the Queen of GreatBritain, residing at Plainfield, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in PaperPrinting and Folding Machines, which are fully set forth in thefollowing specificatiomreference being bad to the accompanyingdrawings,in which Figures 1 and 2, taken together, represent afront-side elevation of a machine embodying my improvements, Fig. 1showing the rear portion of the machine and Fig. 2 the front portion; Fi.3,the back-side elevation of the rear portion of the machine; Fig. 4, arear-end elevation of the machine, the outside gearing being removed;Fig. 5, a longitudinal vertical section of the rear portion of themachine on the line as 00, Fig. 4.; Fig. 6, a detail front elevation ofthe friction device at one end of the paper: roller; Fig. 7, a plan viewof the same; Fig. 8, a plan view of the shifting and brake mechanism forstopping and starting the machine; Fig. 9, a side elevation of the same;Fig. 10, a detail plan of the sheetturning device; Fig. 11, a detachedview of the sheet-turner constructed to be fixed; Fig. 12, a similarview of the sheet-turner in the term of a roller; Fig. l3,adetail plan,on an enlarged scale, of the device for mounting the roller; Fig. 11, adetail plan of a modification in the sheet turning mechanism; Fig. 15,an end elevation of the same; Fig. 16, a side elevation, showing asecond modification of the sheet-turning mechanism; Fig. 17, an endelevation of the same; Fig. lo, a plan view of a third modification ot'the sheet-turning device; Fig. 19, a side elevation ofthe same; Fig. 20,a plan view ofa fourth modification of the sheet-turning device, andFig. 21 a side elevation of the same.

Myinvention relates to certain improvements in web-printing machineswith folding attachment, the object being to print from two rolls on thesame press, and then associate the two printed webs so that they may befolded together, or to print from a single roll, the web being dividedlongitudinally and the two parts associated before delivery tothet'olding mechanism.

I will proceed to fully describe the construction and operation of amachine embodying several parts of my invention, and the specialimprovements which it is believed are new, and which I desire to secureby Letters Patent, will then be pointed out definitely in the claims.

The printing mechanism shown in the drawings is substantially the sameas that shown in Letters Patent No. 221,704, granted to me November18,1879. 1 shall not, therefore, describe in detail the several parts ofthis mechanism, but shall mention them only in a general way, and referto the above-named patent for a more specific description.

The main frame A is of any suitable construction to receive and supportthe entire mechanism for printing. associating, and folding the sheets,all of the devices being mounted in or on this frame.

The rolls of paper B are mounted on a single spindle, I), supported onstandards I) at the front end of the machine. There is but a singlespindle l), but it is made of sufficient length to accommodate two rollsof paper, B, whenever it is desired to print two webs at the same time,both rollsbeing mountedon the same spindle. The rotation of the spindleis regulated and controlled by a friction device, B, and an adjustingdevice, B like those described and shown in my prior patent, mentionedabove, so that both rolls of paper are mounted on and carried by thesame spindle and controlled by a single friction device.

The inking mechanism at the front end of the machine is the same as inmy prior patent, and the web or webs of paper receive the firstimpression from the printing-cylinders O G, as in the same patent, theweb being conducted to these cylinders over rollers c 0. (Shown in Fig.2 of the drawings.) A cutter, 0 is arranged above the latter of theserollers in position to divide the web lengthwise when the printing isdone from only one roll; or, it desired, the cutter may be used todivide all of the webs. This cutteris of ordinary construction, and amore detailed description is not necessary here. The web or webs thenpass over the cylinder D, and between it and a second cylinder, D, thesetwo cylinders constituting the second set of printing-cylinders, the inkbeing supplied by a second inking mech anism like that shown in my priorpatents,and which is fully shown in Figs. 1 and 5 of the drawings inthis case. After receiving the sec- 0nd impression, the webs passunderneath a roller, d, and thence rearward to suitable turning devices,which I will now describe.

The shcet-turucrs E E are arranged diagonally to the path of the webs,about at an angle ot' forty-five degrees, the first one, E, extendingentirely across the machine, and the second one, E, some distance in therear of the former, and extending across only a portion of the machine,at the front side thereof, the distance between the tnrners,taken in thedirection of the path of the webs, being equal to the width of one ofthe webs which is to he turned.

I have shown in the drawings two construclions of sheet-turner. Thefirst one, E, is a stiff bar, such as has been used for a like purposein other machines. The second one, E, is aroller monn ted in suitablebearings, e, which are provided with a friction or tightening device, e,by means of which the ends of the turner are clamped so as to permitjust alittle movement of the roller from time to time, to occasionallypresent a new surface to the paper.

A pasting-blade, F, is arranged just in front of the first sheet-turnerand extends only over the web at the back side of the machine. Thisblade takes paste from a roller, F, which is supplied from afountain,f.The pasting-roller is regularly driven by suitable gearing, and thepasting-blade is driven by eccentric-gears /"f the first of which is onthe same shaft as the blade, while the second is mounted on a suitablestud and is driven by a geacwheehf, on the shaft of one of theinking-cylinders, which engages with a regular gear, f, on the samestud-shaft as the eccentric f This train of gears just described is soarranged as to give aquick movement to the pasting-blade as it isbrought down in contact with the web, and a slow movement (lilting therest of its rotation, so as to prevent the throwing olfof the paste fromthe blade by centrifugal force. Now, if two rolls of paper are used andthe two webs are run through the press side by side, obviously the webat the back side of the machine will be operated on first by the firstsheettnrner, E, which turns this web at right angles to its former lineof travel, as shown in Fig. 10 of the drawings. This web is then carriedout, at the back side of the machine, over the roller Gr, set at rightangles to the printing-cylinders, and passes thence back under theturners to a pair of rollers, G G near the back side of the machine andbelow the turners, as shown in dotted lines in Fig. 4 of the drawings.In the mean time the other web on the front side of the machine has beenturned in the same way by the sheet-turner E, the under side of which issetalittle lower than the under side of the turner E, thereby carryingthe second web a little below the first after it is turned. As will beseen in Fig. 10 of the drawings, this web will be carried out toward theback side of the machine directly underneath the first web, and iscarried over the roller Gthe upper one of the pair just mentioned. A setof tapes, 9, may be arranged on the roller G, and a tape roller orpulleys, g, set near the center of the machine forthe purpose of leadingthe ends of the web through after being turned. The front side of theweb is carried out and around the roller G, where it meets the firstweb, and the two being joined pass through between the rollers G G theextra travel of the first web beingj ust sufficient to bring the twotogether in proper position when associated. In order to secure thisresult with certainty, the roller G is made adjustable back and forth inits bearings. In the drawings I have shown an ordinary adjustingscrew, gfor this purpose; but any suitable device may be employed for thisadjustment. The roller G is also provided with a longitudinal groove, 9,(shown in Ft". 3 of the drawings,) and the revolution of this roller isregtr lated so that the line of paste previously laid on the back webwill always be brought over this groove as the web passes over theroller, thereby preventing the paste coming in contact with the surfaceof the roller.

In order to strengthen the roller and preserve the regular tension uponthe wcb as it passes' around the roller Gr, short sections 9 are left inthe groove. entire, and similar spaces are cnt out of the edge of thepastingblade, so that no paste will be spread on those parts of the webcorresponding to the sections. The two webs, after being associated asdescribed above, are carried downward and inward from the rollers G G asshown in Fig. 4 of the drawings, to cutting and folding cylinders H H H,arranged at right angles to the printing-cylinders, as shown in thefigure of the drawings just mentioned. It is not necessary to describethe construction and operation of these cylinders here, for they areprecisely the same as shown in Letters Patent No. 220,873, granted to meOctober 21, 1879, to which reference is made for a full description. Theassociated webs are acted upon as one by these three cylinders, thesheets being severed and receiving two parallel folds, as described inLetters Patent No. 220,873. The three cutting and folding cylinders aremade of a length twice the width of one of the webs of paper, for apurpose which will be presently explained; but in the operation abovede- IIO scribed obviously the associated webs will be acted upon at oneend only of the cylinders, in this instance the rear end, as shown in Fi3 of the drawings, though this order may be reversed. The twice-foldedsheets as they are delivered from the cylinders are received by suitabletapes, h h, by which they are carried upward and outward toward thefront side of the machine, over a pair of ordinary foldingrollers, I,set at right angles to the preceding cutting and folding cylinders, asshown in Fig. 5 of the drawings, and under an ordinary vibratingcreaser, I, arranged to operate in conjunction with thesefolding-rollers. As the folding sheets are delivered to this foldingmechanism they are creased into the bite of the rollers I'm the ordinaryway, thereby receiving a third fold at right angles to the first two,and are delivered downward into a receivingtrough, J, in front of areciprocating packer, K, by means of which they are delivered, properlyfolded, at the rear end of the machine.

I will 110w proceed to describe an im provement in the mechanism foroperating the vibrating creaser.

The main driving-shaft L is located substantially as in my prior patent,first mentioned above, and is arranged to make one revolution for everysheet of printi n The main drivinggear lis fixed on this shaft at thefront side of the machine, and just outside of it is an eccentric-gear,M, also mounted on thesame shaft, which engages with a similareccentric-gear, M, mounted on a stud-shaft at the front side of themachine, as shown in Fig. l of the drawings. Inside of this lasteccentric-gear, and connected to it, is an ordinary eccentric, m, aroundwhich is arranged the usual strip, which is connected by a rod, m, to anarm, n, attached toarock-shaft,l l,on the frame above the eccentric.This rock-shaft is also provided with another arm, n, outside of theformer, which is connected by a rod, TS, to a crank-arm, i, on therock-shaft t, to which the arm that carries the creaser I is attached.The two eccentricgears M M and the eccentric m are arranged relativelyto each other so that the creaser I will have its quickest motion at thelower part of its descent when it has operated upon the sheet, therebyproducing a quick movement just as the creaser enters the bite of thefolding-rolls and is withdrawn therefrom, while during the rest of itsmovement it will have a comparatively slow motion.

The mechanism constructed and operate 1 as described above will producea paper of eight pages pasted and folded three times.

If it is desired to prepare supplements, or a paper of four pagesinstead of eight, it is only necessary to make the following changes: Inthe first place both webs are led over and turned by the onesheet-turner, E, which obviously will simply turn the webs withoutbringingthem one over the other thence the turned webs, traveling sideby side, are carried to the back side of the machine over the sameroller G, which is made of a sufficient length to accommodate both webs,and thence directly to the cutting and folding cylinders, which operateupon the sheets as they pass through side by side, just as previouslydescribed. Evidently, however, as two folded sheets will now bedelivered from the cylinders, one in frontof the other, (speaking withreference to the machine,) it is nrccssary to provide a second set ofdevices for making the third fold. in the sheets. This mechanism isshown in Fig. 5 of the drawings, in which another set of foldingrollers,1 and a vibrating creaser, 1 are pro.- vided, constructed and operatedprcciselylike therollers I and creaser I described above, and arrangedin front of the latter in suitable position to receive the other set offolded sheets as they are delivered from the other end of thefolding-cylinders, in the same way as already described for the firstset. The sheets folded by this second set ofdcvices are delivered downbetween a set of tape-pulleys, 0, directly below, over which two sets oftapes 0 0 are passed, extending toward the rear of the machine andrunning over tape-pulleys or rollers 0, arranged below the front rollerof the fold-' ing-rollers l, as shown in Fig. 5 of the drawings. Thefolded sheets are carried by these tapes toward the rear of the machineunder the set of folding-roilers first described, where they are turneddownward by suitable curved guides, 0 and are delivered side by sidewith the folded sheets delivered from the rollers I, the carrying-tapesbeing timed to accomplish this purpose. In order to regulate the tapesso as to accomplish this result I place a roller, 0 across the centralportion of the tapes, and make it adjustable vertically, so that if thefolded sheets are delivered a little too quick they may be regulated bybringing the roller against the tapes, thereby making a bend in the pathof the sheets and increasing their travel snfficiently to effect theirdelivery at the proper moment to correspond with the sheets deliveredfrom the other side of the foldingrollers. This roller may be placed ineither the upper or the lower tapes. In the drawings I have shown itplaced in the upper set, as being more convenient.

The arm of the second creaser, I is attached to the rock-shaft N, sothat it is operated by the same eccentric as the creaser l, with thesame results, and the movements of the two creasers are simultaneous.

One of each set of the folding-rollers I l is provided at its front endwith a beveled pinion, by meansot'which therollers are driven throughshafts 71 71 provided with suitable beveled pinions, and driven from themain gear on the main driving'shaft.

The packer K is connected to a slide-bar, 7c,

Fig.5, underneath the receiving-trough, to the front end of which isconnected the lower end of an arm, k, mounted at its upper end on astud. A short arm, k is also mounted. on the same stud and connected tothe arm K, or cast therewith. An eccentric, K, is fixed on the mainshaft, the strap of which is connected by the eccentric-rod k to the armk thereby communicatingthe necessary reciprocating motion to the slidingbar and packer.

The cutting and folding cylinders are driven from the main shaft bymeans of miter-gears 1 l (shown in Figs. 3 and 5 of the drawings,) therollers being carried together at the rear end of the machine, as shownin the same drawings, from which gears the rollers at the back side ofthe machine are also driven, as shown inFig. 3 of the drawings.

In Figs. 8 and 9 of the drawings 1 have shown a device for instantlystopping the machine when the belt is shifted. The main driving-pulley Lis fixed to the main driving-shaft L, and the usual loose pulley, L isarranged by its side in the usual manner, with the customary devices forshifting the band. A brakeshoe, P, is provided for the driving-pulley,mounted on the upperend of an arm,p, pivoted at its lower end to asuitable support, 19, on the floor or elsewhere.

On the reciprocatingrod Q, to which the bandshit'ter is attached, is aninclined or wedgeshaped cam, q, arranged just back of and with itscam-face against the brakeshoe, the relation of the parts being suchthat when the belt is shifted from the driving to the loose pulley thebrake will be set up against the former and instantly stop the machine,and of course will be releasedwhen the ban (1 is shifted back. Theshifting-rod Q is opera ted by arockshaft, Q, at the front side of themachine, provided with hand-levers, as shown in Figs. 1 and 2 of thedrawings.

In the description above I have explained the operation of the machinein connection with two separate webs mounted in rolls on the samespindle; but, if desired, a single roll, with a single wide web for theentire machine may be employed, in which case, however, it will benecessary to bring the cutter 0 into operation for the purpose ofdividing the web centrally,or,in case the sheets are to be foldedsingly, and but one turner used, as described above, they may beseparated by a cutter arranged and operating substantially as shown inmy prior patents above mentioned. Obviously, by increasing the width ofthe machine and duplicating the lltteSSdly devices, more than two websmay be turned and associated, after printing, before cutting andfolding, as described above, and the different webs may even be broughttogether from ditferent printing-machines, if desired.

1 have not entered into a detailed description of all of the gearing andother ordinary de- "ices necessary in the construction of my machine,for their construction and arrangement will be readily understood bythose skilled in the art from the description given above and theseveral figures ot' the drawings.

Figs.14 to 21 show modificationsofthesheetturning devices. The web atthe back side of the machine is designated 1, and that at the front side2. In Figs. 14 and 15 the sheetturners R and R are set at an angle toeach other, with their rear ends inclined inward, the latter being in aplane lower than the former. The webl is turnedoverand nnderthe turnerR,which will cairy it sidewise forward, thence over a roller, 0', set atright angles to the printing-cylinders, thence toward the back side ofthe machine to another roller, 4, whereitmeets the web 2, which in themeantime has been turned under and over R, whence it is carried sidewiseinward to the roller *r, where it is associated with'web 1, and the twotogether,

passing over this latter roller, are carried on to the cutting-cylindersbelow.

In Figs. 16 and 17 another modification is represented, which is similarto the preceding, except that the web 2 is turned under the turner Itinstead of over it, and is carried thence to a third roller, 4", insteadof to the roller r, and the webs are associated after they pass theroller 1, as shown in Fig. 17 of the drawings.

In Figs. 18 and 19 the turners S S are arranged vertically. The webs 1and 2 pass between the rollers 88 before reaching the turners, whichhold them in proper position. The web 1 passes around the outside of theturner S and the web 2 around the outside of the turner S, and afterpassing the turners both webs are carried directly to thecuttingcylinders, where they are associated. In this modi fication thecutting-cylinders must also be set in a'vertical position. In Figs. 20and 21 a modification is shown varying slightly from the preceding. Theturners are, however, set close together, and the two webs pass betweenthem, being thus turned and associated at the same time, and passingthence directly to the cutting-cylinders. In this modification, however,the tnrners and cutting-cylinders must be set slightly inclined towardthe front end of the machine, for it will be noticed that the turnersare located at the inner margins of the webs,and thereforein twistingthesheets there will be a slight change in their relations as they passfrom the turners, while in the former case, the turners being locatedcentrally of their respective webs, the latter will be turned, so thatas they leave the turners they will move in planes perpendicular totheir former paths.

in using any of these modifications it will, of course, be necessary tochange correspondingly the position ot'the parts operating in connectionwith the cutting-cylinders. The webturners first described and shown inFig. 10 ot' the drawings may bemountedin a frame in such a way as to beadjusted with reference to each other to suit webs of different width.This may be accomplished by a variety of devices not requiringdescription.

I am aware of English Patent No. 3,056 of 1875, in which the web ofpaper is turned by a roller or shaft placed in an inclined positionacross its path; and I do not claim anything shown in said patent.

Having thus described myinventionflvhat I claim as new, and desire tosecure byLetters Patent, is

In a web-perfecting printing-press, mech anism, substantially asdescribed, for carrying more than one independent web or one splitlongitudinally, in combination with a plurality of independent turnersoperating on each web separately to bring the webs over each other, andmechanism, substantially as described, arranged to increase the distancetraveled by one or more of the webs after leaving the turners to bringthe sheets in proper position when associated in one signature,substantially as described.
